Title: Ski boot mounting plate on safety binding - is attached to ski by tapered location collar which pulls out under given loading
Inventor: SCHROEDER WALTHER
IPC: A63C9/086
Filed: 1977-02-12
Abstract: A safety ski binding includes a ski boot mounting plate which is normally located by a circular flange plate (2) that is attached to the top face of the ski. The tapered sleeve (2, 3) on the flange plate is placed inside a matching seat on the under side of the mounting plate. When the axial force applied to the two location elements (3, 10) reaches a minimal value, they disengage and thus allow the ski boot mounting plate to disconnect itself from the ski. An anchor cable which is stored inside a coil chamber (30) on the ski surface, ensures that the ski boot and the ski remain linked at a safe distance.

Title: Armoured security vehicle with servo-opened side doors - has separate locked compartments opened by individual keys with unauthorised opening triggering alarm
Inventor: WARNAT GERD-RUEDIGER
IPC: B60P3/03
Filed: 1977-03-22
Abstract: The armoured security lorry has the load space secured by armoured flap doors (6) which open to give access to a series of separate armoured compartments, rigidly fixed to the lorry. Opening the doors operates the alarm so that thieves have no time to force the separate compartments. The doors are coupled to the ignition system so that they remain locked when the lorry is left. The doors are only opened by internal servo rams. Customer security is increased by only the sender and receiver of each compartment having keys.

Title: Continuous separation procedure for flotsam - dams floating substances and separates them by use of side flow extraction duct
Inventor: WEIKOPF MANFRED
IPC: E02B15/06
Filed: 1977-05-14
Abstract: The continuous separation procedure for flotsam is for channels, and drainage systems esp. those which have changing water levels. In the channel or drainage system, only the light substances on the fluid surface (17) are dammed. They are then separated from the fluid by an overflow and then carried away. The light substances are dammed without any significant hindrance of the fluid passage. To effect this sepn., the channel section (1) has an adjacent outlet (2) for flotsam removal. An immersion damming device (4) is inserted behind this outlet (2) viewed in the the flow direction and there is also an overflow device.

Title: PBX extensions monitoring device - is designed to trip signal when charge pulse spacing falls below given value
Inventor: PRUEFLINGER HELMUT
IPC: H04Q3/62
Filed: 1977-06-08
Abstract: Extensions on a telephone PBX network have different entitlements, and the device monitors calls to the public telephone network which are dialled directly by the extensions. There are several devices which are connected to individual exchange lines. The devices test the spacings between charge pulses, and when they are shorter than a certain value, and in absence of the extension entitlement, the devices trip a signal. The circuit timing device may be used for a variety of different functions.
Patent DE-2729074-A1 (DE)
Inventor: KOOPMAN NICHOLAS GEORGE
IPC: H01L23/373
Filed: 1977-06-28
Abstract: The operational heat of a semiconductor chip (1) is transferred to a cooling can (5) by means of a metal cushion (7). The metal cushion is permanently connected to the can or the chip on one side whilst its opposite side is in loose contact. This creates a connection of high thermal conductivity without exposing the chip to inadmissible mechanical stresses. <IMAGE>

Title: Endless twisted wire strand cable - has core enclosed by five strands only so strands abut the core when cable is subjected to tensile stress
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: D07B1/18
Filed: 1977-06-30
Abstract: Cable has its core ends brought into a abutment, and instead of the usual six strands used for known wire cables only five twisted wire strands are used, so that when the endless cable is exposed to tensile stretch the wire strands do not abut one another but the core.

Title: Safety floor anchor for cattle tie up - has T=shaped block fitting into cross-shaped opening on top of hollow rods to allow passage of link chain
Inventor: SCHINDELE REINHARD
IPC: A01K1/064
Filed: 1977-07-01
Abstract: The safety floor anchor has a cubic or cylindrical hollow body with a cross-shaped opening at the top. This allows the passage of a link chain and permits the shift of one of the chain links in one or more of the slots so that a chain link can be placed transverse to the slot above and below the slot, so to fix the chain in the longitudinal direction. The open T-shaped part of the opening in the top is closed by a corresponding, T-shaped block. Consequently, the introduced chain element cannot be moved laterally nor can it be involuntarily set free.

Title: Container for separate storing of two materials - has hollow screw closure with cutting edge to break membrane separating two materials before discharge
Inventor: OTTINA LUIGI DR
IPC: B65D81/32
Filed: 1977-12-05
Abstract: The device has containers for separate storage of two materials of which at least one is a liquid. It is used for producing a product when one material is mixed with, or dissolved in the other before the storage container is opened. The device includes a first container and a hollow closing part for the first container.

Title: CRT oscilloscope for investigating wave shape at different points - uses balanced difference vertical signal inputs with beam switch selecting plates
Inventor: BEESLEY JOHN
IPC: G01R13/26
Filed: 1978-05-02
Abstract: The oscilloscope can reproduce a multiple phase wave form simultaneously, where the phase displacements of the various reproductions are accurately aligned. It is useful when wave form is being compared at various points in a complex circuit. The phases are sequentially swept to within the limit of persistency of the tube. The circuit consists of four vertical balanced difference inputs (18) which are each connected to an amplifier (CH1-4). Each amplifier feeds a beam switch (14). The switch will sequentially pass the amplified signals to the vertical deflection plates of a CRT (17) selectively. The switch controls an intensity modulator and the switching speed is such that each waveform appears continuously.

Title: Impact absorbing chassis for car - has asymmetric strength bars to deflect non-central impacts
Inventor: BRAESS HANS-HERMANN DIPL ING D
IPC: B62D21/15
Filed: 1978-12-14
Abstract: The impact absorbing chassis has one side weaker than the other so that the impact forces are deflected away from the passenger compartment. Additional diagonal struts (13, 14) add to the off-centre effect and a sloping deflection strut (12) behind the bumper (1) guides the deflected force. The system copes with offcentre impacts as well as frontal ones. The weaker side has collapsing sections (19) included in the chassis frame, as have the diagonal struts. The bumper is linked to the chassis by conventional elastic supports. The additional impact protection does not add greatly to the weight of the vehicle nor to the cost.

IPC: B29B15/00
Filed: 1978-12-22
Abstract: A method of producing endless drive belts of natural or synthetic rubber with thread-shaped embedded strength carriers which preferably extend in the longitudinal direction. This method relates especially to multiple V-belts and similar belts having longitudinal ribs extending continuously over the inner periphery or circumference thereof. A raw belt member is built up in upside-down sequence of layering, and is placed into an outer form or mold, in which it is formed-out and vulcanized. The belts are then turned or folded or rolled over into the use condition thereof. The raw belt member, which is produced oversize with respect to the outer form or mold, is retracted, pulled-in, or drawn-in to an outer diameter corresponding to the smallest inner diameter of the outer form, and is expanded within the outer form to, or essentially to, the original outer diameter thereof. The raw belt member may be subjected to a pressure gradient, drop or differential effective from the outside toward the inside for retracting, pulling-in or drawing-in the diameter thereof. The raw belt member has strength carriers of synthetic polymers which shrink in the heat, and may be subjected to an elevated temperature for retracting, pulling-in or drawing-in the diameter thereof.
